Question: How do I edit an expression

In Maple 11, the expression pallette has the following availble for click and insert:

{-x   x<a

{x   a<x

This above is combined in a single brace. I would like to add a third line to the single brace set, but I can not figure out how to do this. I tried using the piecewise command and converting it to 2D but it errors out:

 piecewise(x < -1, x^3,-1 < x <1, x,x >= 1, 1-x)

Error, unexpected relational operator


Can one of you Maple Gurus' help?
